To all whom it may concern.-

Z611 of the United States of America, residing at 112 St. James street, in the city and district of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Flexible Supports for Machines Mounted on an Axle, of which the following is a specification.

The invention relates to improvements in flexible supports for machines mounted on an axle, as described in the present specification and illustrated by the accompanying drawings, that form part of the same.

The invention consists, essentially, of a rotatable axle, a machine mounted thereon, a

rigid member independent of said axle, a subsidiary rigid member independent of said axle, means connecting said machine with said rigid member, and a member pivotally secured to said machine and connecting said subsidiary rigid member thereto.

The objects of the invention are to devise a means of supporting a machine on a rotating axle, in which the varying positions of a frame and an axle in relation one to the other shall be accommodated without jarring the machine, and to provide in such devices compensating features whereby thestress on one group of parts is relieved by another group of parts, thus obtaining durability and to secure resiliency in operation.

In the drawings, Figure l is a perspective view of the invention applied to a powertransmission device mounted on an axle journaled in a vehicle-truck. Fig. 2 is an enlarged view showing a front elevation of the device and portion of the truck-frame in cross-section.

Referring to the drawings, a is the axle, here shown as forming part of the runninggear on a railway-car.

b designates beams forming part of the truck-frame.

c is a bar secured at each end to a beam 1) and preferably arranged in alinement with the axle. The bar 0 forms the fixed support for the transmitting device mounted on the axle therebelow and has the central slot (1 substantially oval-shaped.

It must be understood that in this brief description of the transmitting device I do not wish to confine myself to any one type of machine and that without departing from the spirit of my invention it may be applied to any form of machine mounted on a rotating I shaft and requiring flexible connection with a fixed support.

7b is an upright stud fixedly secured to the top of the transmission-casing e and encircled for the greater part of its length by a removable sleeve 'L. j is a hole through the stud h in proximity to the to thereof and immediately above the washer ic.

Z is a cotter-pin inserted through the hole and locking the said washer and sleeve on the stud h. The stud h, encircled by the sleeve i, extends upwardly through the slot d in the fixed supporting-bar c. v

m is a shoe mounted on the upper projecting end of the stud h on the sleeve 7 and resting on the fixed supporting-bar c and having 116 lugs n projecting downwardly below the arc.

0 designates bolts securing the bars 5 to the bottom of the lugs n beneath the bar 0.

It will be thus seen that the retaining-support for the transmission-casing is provided in the stud h, projecting through the fixed bar 0, and all movements of the axle in its bearings are accommodated by the movement of the stud h in the slot cl. 1) designates subsidiary hanger-bars bolted to the bar 0 and rigid therewith and extending laterally therefrom and having the holes 9 and 1 therethrough toward their outer ends.

s is an car from the offset portion f of the casing e, and t is a link pivoted on the lug s and pivotally secured at its upper end to the yoke u. The yoke it extends to each side of said link in a downward direction and at its extremities has the slots 1).

w designates eyebolts having the rings x encircling the bars 29 between the holes q and 1-.

y designates cotter-pins inserted through the holes g and 1* at each end of the rings as and retaining said rings-on the rods 19.

2 designates washers between said *cottere is a casing having the offset portion f and pins and said rings.

The eyebolts to extend through the slots 12 of the yoke u and at their lower ends have the washers 2 and nuts 3 secured thereon.

4 designates spiral springs encircling the eyebolts w between the yoke 11. and the washers z, the said washers and the said yoke forming the stops for said spring at each end thereof. This arrangement of yoke, spring, and eyebolts connected with the subsidiary supporting-bars 1) forms a means of constantly returning the stud h to its normal position in the slot, and in any change of position caused by the varying movements of the axle, of a vehicle in travel the, jarring and j olting on the machine supported will be reduced to a minimum.

The utility of a device of the class described is well known in supporting transmission devices in vehicles and supporting motors and dynamos on rotating axles. In supporting motors and dynamos it is essen tial to have a device which will ease off the efiect of a sudden jump of the axle when ad .justably journaled, asis the case in railwayis not properlytaccounted for, and in the pres.

ent invention it will be readily seen from the description that the yoke acts as an equalizer in any sudden shock by the tilting of the axle and prevents that shock from reaching the parts of the. machine to any serious extent and in addition relieves the strain on the main supporting-stud, and this is particularly essential when the lubrication has been neg lected and the pull on the stud abnormal.

The, sleeve on. the main supporting-stud will render the repair to the stud very simple, as the sleeve may be replaced from time to time instead of removing the casing in order to. renew the stud.

The portion of the supporting-stud is herein described as upright, with the fixed sup: porting-bar. directly over the machine; butit must be understood that the casing may be supported in any position suitable to the. needs of the occasion and the fixed sup portingrbar arranged accordingly. This arrangement of yoke-spring. and eyebolts connected with the subsidiary supporting-bar p forms a means of relieving the stud h of the weight of the shaft, and in any change of position caused bythe varying movements of the axle of a vehicle in travel the shock on the machine supported will be reduced to a minimum.

The weight of the shaft and the hammerblow delivered tethe. stud h. as a consequence of this weight when a moving vehicle passes over inequalities in the roadffor instance, a car truck passing over switches, frogs, or loose joints in the track, together with the continuous axle. playcauses considerable wear in the stud it unless some provision is madev to take the unbalanced weight and shock, as explained.

If the stud h is permitted to wear to any extent, the angularity of the universal joints is increased, the effect of sudden shock is emphasized by reason of the extra motion between parts of the transmission itself, due to wear on retaining-surfaces, and as a consequence the life of the transmission is materially shortened.

It is required, however, that the transmission-support shall not in any way interfere with the relative motion between vehicle frame and axle and shall be. unaffected by the application of brakes, wear in axle-boxes, and shall offer no obstacle to the speedy changing of wheels.

What I claim as my invention is' 1. In a device of the class described, the combination with a rotatable axle, a casing mounted thereon and a rigid supporting, member independent of said axle, of a sub; sidiary rigid supporting member independent of said axle, means connectingv the aforesaid rigid member with said cas'mg, and a member pivotally secured to said casing and;
